Suppose you have a 2.0 molar solution of sodium hydroxide (naoh), and you need 65 ml of 0.6 molar naoh. how should you make this
nalin [4]

The given molarity of sodium hydroxide solution = 2.0 M

The required concentration of sodium hydroxide is 65 mL of 0.6 M NaOH

Converting 65 mL to L:

65mL*\frac{1L}{1000mL} =0.065L

Calculating the moles of NaOH in the final solution:

0.065L * \frac{0.6 mol}{L} =0.039mol

Finding out the volume of 2.0 M solution taken to prepare the final solution:

0.039 mol * \frac{1L}{2.0mol}=0.0195L*\frac{1000mL}{1L} =19.5mL

Therefore, 19.5 mL of 2.0 M NaOH solution and make it up to 65 mL to prepare 0.6 M NaOH solution.

How does the value of kc in n2o4(g)⇋2no2(g) kc=[no2]2[n2o4] depend on the starting concentrations of no2 and n2o4?
Vlad [161]
<h3><u>Answer;</u></h3>

The value of Kc does not depend on starting concentrations.

<h3><u>Explanation;</u></h3>
  • <em><u>At constant temperature, changing the equilibrium concentration does not affect the equilibrium constant, because the rate constants are not affected by the concentration changes. </u></em>
  • When the concentration of one of the participants is changed, the concentration of the others vary in such a way as to maintain a constant value for the equilibrium constant.

Calculate the molar mass for HCN.<br> 0.2703 g/mol<br> 2.703 g/mol<br> 27.03 g/mol<br> 270.3 g/mol
elixir [45]

Answer:

27.03 g/mol

Explanation:

Molar Mass of HCN

Mass of Hydrogen : 1.008

Mass of Carbon: 12.01

Mass of Nitrogen: 14.01

Molar Mass of HCN =

1.008 + 12.01 + 14.01=

27.03 g/mol
